j vPoRizER FOR LIQUID-EURL.A BURNERS.

Application ined December 14, 1921.` serial No. 522,452.

To all/whom t may concern:

Be it known that I, JULEs EUGNE MALI- VERT, `a citizen of the FrenchRepublic, of 9 and 11 Rue du Telegraphe, Paris, France, have invented anImproved Vaporizer for Liquid-Fuel Burners, of which the following is afull, clear, and exact description.

This invention has for its object an improved gasifyingdevice forsoldering lamps, 10 soldering-irons, chatting-dishes and other similararticles in which gasoline or petro leum is used. It is adapted toprevent the carbonization of the cotton wick, bringing by capillaritythe fuel fromthe reservoir to the burner, bv spacing said wick from theburner and thus insuring the proper functioning of said wick at alltimes;

To prevent the liquid being drawn from the resevoir in the wick-carryingtube and in the burner, by ensuring the complete conversion of the fuelinto gas before it is admitted to the burner.

This yapparatus isV substantially characterized by a special gasifyingsleeve, adapted to produce the complete vaporization of the fuel and athrottle-washer separating this sleeve from the wick and adapted toregulate and limit the admission of the fuel to the gasifying device.

In the preferred form of carrying out the invention, the sleeve is madeof a sheet of metal which is corrugated and constitutes a kind oftubular bundle.

The washer is perforated with one or more small orifices and is placedatwise against one end of the sleeve on the side where is admitted theliquid fed by the wick engaged into the reservoir. p

The combustible liquid drawn by capillarity in the tubular bundle isdivided therein in very small streams or veins so that its perfectvaporization is therefore ensured and preventing any drop of liquid fromever reaching the burner. v

The invention will be described hereafter, by way of example, in theaccompanying drawing in which:

Fig. l shows aI part. in front view, the essential elements of theimproved gasifying device.

Fig. 2 is an end view of the same.

Fig. -3 is a front view of the gasifying sleeve.

Fig. 4 is an end view of this sleeve.

Fig. 5 illustrates this gasifying device fittedin a solderiiigron,` lthe latter being 'I y partly in section. Q As illustrated in thedrawing, thisv gasifying device is constituted by va cylindrical sleevea composed ofy a kind of tubular bundle arranged about a central channelal.

This channel can remain free and empty, as illustrated or it can befilled by a ,metal rod so las not to leave any passage of irnportantVcross-section. p

This sleeve a is obtained by corrugating a very thin sheet of metal,then by bendingit about a mandrel.

On one of the ends of the sleeve is .fitted fiatwise a washer Z)provided at its center with a small orice b1 (or more).

'When this gasifying device is iittedin a soldering-iron for instance,as shown in Fig. 5, the wick c extending from the reservoir d yandpassing in the tube c comes against the washer b in front of which isplaced the sleeve a arranged in the bushV 7 y of the soldering-iron.

In this position, the gasifying device is situated above the ordinaryheater q and its front end is situated behind the spraying nozzle 7L.

The gasoline contained in the reservoiry gasifying sleeve where it isvaporized when it reaches the spraying nozzle. l

tiring its displacement the liquid reaches the gasifying device alreadyin a very di` vided condition, then, owing to its contact with thesleeve a which .presents` a large surface, it is still better vaporized,either under the action `of the heat of the heater g, or under the`action of the natural heat of the bush f when the apparatus is in operation.

The forms, details, accessories, materials and dimensions of thisgasifying device may of course be varied without departing thereby fromthe principle of thel invention.

Claims- 1. An improved gasifying device for soldering lamps, comprisinga member hav-A ing a central passage and longitudinal hollow ribsopening into the central passage, and a throttle-washer at the inlet endof the said member.

2. In a device of the character described, a gasifying sleeve-likemember formed of thin corrugated metal and having aY disk provided witha small central opening secured to one end thereof.

3. The combination with a soldering iron having a wicktube and a chamberabove the wick-tube, of a corrugated. sleeve-like,

member arranged in the said chamber, and a disk having' a small opening`and at the lower inlet end of the said member and with which the wickis adapted tov engage.

4. The combination with a lamp comprising a liquid fuel reservoir, aburner, and a wick interposed therebetween, ofa, vaporizer interposedbetween the wick and the burner, yand means for restricting the flow offuel from the wick to the Vaporizer, said means comprising' anstpertured disk-like member between the vaporizer and wick and inengagement with the wick.
